Hi there, I dont know how long my herniation was, but I didnt have a patch either, cos it can somtimes cause scar tissue to build up onto it.
I was back to work after 8 weeks, on a phased return, and yes kids do bounce back quicker than us, but I would take it one day at a time with him.. He will soon start getting on your nerves, and then you will know that he is getting bored and needs to go to school. Also the school should help you like the others have said. Either speak to your school SENCO (Special Educational Needs Coordinator or head teacher and figure something out for him.
They can give him stuff to do at home and reading books etc. Got my follow up MRI tomorrow.
